SPRING-LEAF COVER OILER.

Application filed November 22, 1926. Serial No. 150,022.

This invention relates to vehicle spring covers and especially to a means for permit-v ting oil to be introduced from time to time to lubricate the enclosed spring.

It is very desirable to provide an inexpensive and yet very substantial and thoroughly practicable device permanently combined with the cover organization in such manner that oil may be readily introduced.

An object is to provide a device which is easily operable as a valve and which presents no material surface obstruction likely to be caught in a cleaning cloth used about the installed parts.

Spring covers of the type here concerned are usually made of one or more fabric, or other pliant enveloping layers and a heavy, oil reservoir of felt next to the spring, and an object of my invention is to solidly anchor a valve device on this cover whether it has one or more of the layers of fabric and felt making up its structure.

Additional objects, advantages and features will be made manifest in the following specification of an embodiment of the invention as herewith illustrated; it being understood that modifications, variations and adaptations may be resorted to within the spirit, scope and principle of the invention as it is here claimed.

Figure 1 is a cross-section of a spring cover showing its applied oiling valve.

Figure 2 is a plan of the device.

Figure 3 is an enlarged section.

Figure 4 is an enlarged section showing {aha anchor plate as below and fast on a felt A laminated spring system S is shown as encased in a form of oil reserving and leaf protecting cover usually including an outer flexible sheath 2, as of fabric or leather, and an inner jacket layer of felt 3 capable of absorbing and thus reserving a supply of lubricating oil for the spring leaves.

The oiler or valve includes non-corrosive partswhich, for low cost, are in the form of stiff metal washers 5 and 6 clinched upon an intervening body of the enveloping cover by a central rivet 7 about which the outer washer or plate may be turned by pressure of a thumb or finger, or by a simple tool or implement if need be.

The outer plate has an eccentric oil hole 8 which may be turned to register with a complementary oil hole 9 in the cover body.

Preferably the hole 9 is lined by an eyelet 10, which also passes through the inner plate 6 so that this is solidly anchored to the cover body.

In Fig. 3 the inner plate is clinched against the cover sheath and in Fig. 4 it is sented to catch in a cleaning cloth or brush used to clean the cover on the spring.

The plates 6 and 5 are duplicates, are connected by the center rivet 7 and the inner plate 6 is held by the anchoring eyelet which constitutes a conduit through the cover body. Hence a valve or oiler consists of only three differently shaped pieces, all of which are of common stock material; the disk washers being punched to provide the oil hole.

The interior of the eyelet 10 may be internally threaded, as here shown, for attachment of a grease injector if andwhen desired.

What is claimed is:

1. A leaf spring protecting device including an enclosing means, and a valve means for introducing oil thereinto and including an inner disc and an outer disc each having a registerable oil hole, and means centrally clinching the discs on an intervening body of the enclosing means, said outer disc having unlimited rotation on the clinching means and operative to close the hole in the inner disc at all positions except when the holes are registered for oiling.

2. A leaf spring protecting device includ ing an enclosing means, an oiling valve for introducing oil thereinto and including an inner and an outer disc each having an oil hole disposed close to its axis, and a clinching means fastening the discs in position and consisting of a central rivet on which the outer disc is turnable without limitation to register the oil holes.

3. A leaf spring protecting device includ-, ing an enclosing means, an oiling valve including an equal size outer disc and an inner disc clinched by a central pivot upon an intervening body of the enclosing means, the outer disc being turnable to register holes in the discs, and holding means connecting the inner disc to the said body independently of the pivot, said central pivot forming the sole clinching means for the outer disc,

which latter has unrestricted rotation and uncovers the hole in the inner disc only when registered.

4. A leaf spring enclosing means, an oiling valve having an outer turnable disc and an inner disc, a central rivet clinching both of the discs upon an intervening body of the said means, the outer plate having an oil hole, and an eyelet fastening the inner plate and forming a conduit with which the hole in the outer turnable plate is registerable, the outer disc having unlimited rotation on its clinching rivet and at any position closing the eyelet except when in oiling position.

5. In combination, a leaf spring enclosing envelope, a rivet passing through a thickness of the envelope, -twin coextenslve CllSC Washers coaxially mounted upon the rivet,
